I trying to get the music to the outside speakers
By the speakers cable plugged into the computer! :-) \// //\
I dont understand your question exactly. Speakers work off changing voltage, similar to whats in the wall but different. Anyways you have a electrical signal sent to the speaker, which changes which is how you get speaker to slap. Once it goes through speaker it goes through ground wire and thats it. Circle of life battery, load, fuse, ground
